Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to an ecological dam slope downstream of a gravity dam. Background Art

[0002] A gravity dam is a large concrete or stone structure that is usually used to block the flow of water and store water in a reservoir. They rely on their own gravity to resist the water pressure, hence the name gravity dam. Gravity dams are commonly used in hydroelectric power stations, irrigation systems, flood control projects, and more.

[0003] For example, a Chinese invention patent (CN117604962A) discloses a system and method for creating an ecological environment on the downstream slope of a gravity dam, which states: "On the basis of the existing concrete gravity dam structure design in the field of water conservancy and hydropower dam engineering, the vegetation concrete structure, greening sprinkler irrigation and other technologies are deeply combined to complete the ecological construction of the downstream slope of the gravity dam." It also states: "In traditional water conservancy projects, the construction of gravity dams mainly focuses on the safety of the building itself. The exposed concrete surface of the dam body is always maintained throughout its life cycle, which cannot meet the landscape and greening needs of the downstream dam slope. With the increasing maturity of building design, construction technology and engineering management, owners are focusing on the overall landscape construction of the hub area to create a preferred scenic spot suitable for local residents to relax and travel. Therefore, it is particularly necessary to incorporate the dam that occupies the main field of vision of the hub area into the landscape planning." Technical issues.

[0004] To sum up the above, it can be known that in the prior art, water from the upstream of the gravity dam is used to irrigate the ecological dam slope downstream of the gravity dam. However, this method has the following technical problems: there are substances such as aquatic plants and mud in the traditional water flow, and directly extracting water from the upstream of the gravity dam through a pipeline can easily cause blockage and damage to the pumping components, thereby increasing the frequency of subsequent maintenance and the workload of maintenance personnel. For this reason, the present application proposes an ecological dam slope downstream of the gravity dam, which provides a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content

In the process of water extraction, the flow of water drives the fixed plate to move, thereby driving the rotating shaft to rotate, and then driving the cleaning brush to rotate, so as to scrape and clean the mud, sand, and aquatic plants attached to the bottom of the fixed shell. In addition, the movement of the cleaning brush will further disrupt the surrounding water flow, which has a certain driving effect on the fish and shrimp in the water, thereby reducing the extraction of fish and shrimp during irrigation, which in turn causes damage to the ecological environment and protects the ecological environment. At the same time, the uniform watering of the sprinkler is beneficial to plant growth, thereby promoting ecological balance.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] As described in the background technology, the traditional water flow contains aquatic plants, silt and other substances, and directly extracting water upstream of the gravity dam through pipes can easily cause blockage and damage to the pumping components, thereby increasing the frequency of subsequent maintenance and the workload of maintenance personnel.

[0031] In order to solve this technical problem, the utility model provides an ecological dam slope downstream of a gravity dam, which is applied to the ecological dam slope downstream of a gravity dam to reduce blockage of irrigation-related components.

[0033] The dam body 1 comprises a dam body, an irrigation mechanism 2 is arranged outside the dam body 1, a maintenance mechanism 3 is arranged outside the dam body 1, a receiving block 4 is fixedly connected to the outer wall of the dam body 1, a protective fence 5 is fixedly connected to the top of the receiving block 4, a fixing frame 6 is fixedly connected to the top of the receiving block 4, and plants 7 are filled inside the fixing frame 6;

[0035] The utility model provides an ecological dam slope downstream of the gravity dam. In the process of extracting water flow, the flow of water pushes the fixed plate 16 to move, thereby driving the rotating shaft 15 to rotate, and then driving the cleaning brush 26 to rotate, so as to scrape and clean the mud, sand, aquatic plants and the like attached to the bottom of the fixed shell 14. In addition, the movement of the cleaning brush 26 will further disrupt the surrounding water flow, and have a certain driving effect on the fish and shrimp in the water, thereby reducing the extraction of fish and shrimp during irrigation, thereby damaging the ecological environment and protecting the ecological environment. At the same time, the uniform watering through the sprinkler 12 is beneficial to the growth of the plant 7, thereby promoting the ecological balance.

[0036] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0037] Embodiment 1:

[0038] Please refer to Figure 2-Figure 7 , an ecological dam slope downstream of a gravity dam, comprising:

[0039] The inner wall of the water outlet pipe 10 is fixedly connected with multiple branch pipes 11, and the interior of one branch pipe 11 is fixedly connected with multiple nozzles 12. The multiple nozzles 12 spray water to irrigate the plants 7, thereby improving the survival rate of the plants 7, avoiding manual watering, and reducing the labor of subsequent maintenance. The water outlet pipe 10 is fixedly connected to the inside of the dam body 1, and the branch pipe 11 is fixedly connected to the inside of the dam body 1.

[0040] The outer wall of the water inlet pipe 9 is fixedly connected with a reinforcement block 13, which improves the stability of the water inlet pipe 9. The reinforcement block 13 is fixedly connected to the outside of the dam body 1, and the end of the water inlet pipe 9 away from the water pump 8 is fixedly connected with a fixed shell 14. The interior of the fixed shell 14 is rotatably connected with a rotating shaft 15. The outer annular array of the rotating shaft 15 has a plurality of fixed plates 16. The fixed plates 16 use the flow of water to drive the rotating shaft 15 to rotate, thereby improving the energy utilization efficiency. The outside of the fixed shell 14 is provided with a plurality of filter holes 27. The filter holes 27 reduce the entry of solid matter into the interior of the water inlet pipe 9, thereby reducing the risk of the water inlet pipe 9 being blocked.

[0041] The two ends of the rotating shaft 15 are respectively fixedly connected with connecting plates 17, the bottom end of the connecting plate 17 is fixedly connected with a protective frame 18, the upper surface of the inner wall of the protective frame 18 is fixedly connected with a fixed barrel shell 19, the interior of the fixed barrel shell 19 is fixedly connected with a spring 24, the end of the spring 24 away from the fixed barrel shell 19 is fixedly connected with a sliding rod 25, the sliding rod 25 is slidably connected to the inner wall of the fixed barrel shell 19, the end of the sliding rod 25 away from the spring 24 is fixedly connected with a cleaning brush 26, the cleaning brush 26 cleans the bottom area of ​​the fixed outer shell 14 to prevent solid matter from being affected by the water flow and adsorbed on the bottom of the fixed outer shell 14, thereby blocking the filter hole 27 and affecting the irrigation, thereby reducing the labor of later maintenance.

[0042] Through the above structural design, in the process of extracting water flow, the flow of water pushes the fixed plate 16 to move, thereby driving the rotating shaft 15 to rotate accordingly, and the rotation of the rotating shaft 15 drives the connecting plate 17 and the protective frame 18 to move synchronously. With the movement of the protective frame 18, the contact position of the cleaning brush 26 with the outside of the fixed shell 14 changes. In the process of moving within the bottom range of the fixed shell 14, the closer to the bottom position farthest from the rotating shaft 15, the spring 24 is stretched, and the sliding rod 25 slides inside the fixed barrel shell 19, so that the cleaning brush 26 always keeps close to the bottom of the fixed shell 14. When the cleaning brush 26 is away from the bottom of the fixed shell 14 and the distance from the rotating shaft 15 is farthest, the cleaning brush 26 is moved away from the bottom of the fixed shell 14. 5, the spring 24 gradually returns to the normal state, and then pulls the cleaning brush 26 through the sliding rod 25 to keep it close to the bottom position of the fixed shell 14. After the cleaning brush 26 leaves the bottom range of the fixed shell 14, the cleaning brush 26 moves around the outside of the fixed shell 14 for a certain distance and then returns to the bottom range, and then cleans again, and the mud, sand, and water plants attached to the bottom of the fixed shell 14 are scraped and cleaned. After entering the fixed shell 14, the water enters the inside of the water inlet pipe 9, and then enters the inside of the water outlet pipe 10 through the water pump 8, and then disperses into each branch pipe 11, and is sprayed out by the nozzle 12 to water the plants 7.

[0043] Embodiment 2:

[0044] The ecological dam slope downstream of the gravity dam provided in Example 1 is further optimized, specifically, as follows: Figure 4 As shown, the maintenance mechanism 3 includes a step 20 fixedly connected to the outer wall of the dam body 1, and a railing 21 is fixedly connected to the outer wall of the step 20. The railing 21 provides a gripping position for the operator when walking on the step 20, thereby improving the safety of the operator's movement.

[0045] The maintenance mechanism 3 also includes two protective plates 23 fixedly connected to the receiving block 4 on the side close to the step 20. A plurality of U-shaped steel frames 22 are fixedly connected to the receiving block 4 on the side close to the step 20 and between the two protective plates 23. The U-shaped steel frames 22 facilitate the operator to walk onto the receiving block 4. At the same time, the protective plates 23 prevent the side wind from affecting the operator who is climbing, thereby improving the safety of the device.

[0046] With the above structural design, the operator can go to the position that needs repair via the ladder 20, and then further reach the receiving block 4 close to the position that needs repair via the U-shaped steel frame 22, and then repair the damaged position.
